I've been building a map to display impervious surface polygons: http://freeforthepicking.com/imagery/kmlmap4.php?q=1101850&Submit=Search
My polygons were converted from arcview shp files using shp2mysql into Geometry entries in a MySQL geodatabase. From there, the shapes are called by php and dumped into a KML file based on user-entered information, and then that KML is displayed as an overlay. Okay, so: the polygons in Arcview and the polygons displayed in my maps view are different, the ones in the API are simplified: vertexes missing etc. So, I check the KML file, and it looks good: the polygons when displayed in google earth look fine. So, I deduce that the polygons MUST be being simplified when the coordinates information is taken into Google Maps. Between the two sets of polygons, the smallish polygon on the right building is rectangular in before (arcview), but that same polygon in after (google maps) is distorted in its upper righthand corner. Similarly, the polygon for the main building in before has sharp corners and is mutually exclusive with the polygon for the parking lot - whereas in the google maps version it is a misshapen tetragon that overlaps with the parking lot polygon in the lower left side. My question is: why, how, and what can I do to abrogate this simplification (if anything). Below are links to the before and after information for the above polygons as well as a link to the KML file which shows the coordinates and is getting mistranslated/interpreted above. Thank you to anyone how can provide insight into this challenge: Before: http://freeforthepicking.com/imagery/before.jpg After: http://freeforthepicking.com/imagery/after.jpg KML: http://freeforthepicking.com/imagery/KMLs/1101850isu.kml Yours Gratefully, Dominic --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
